Servo full range, EdgeTX/ELRS

[joortiz22]

For some reason I cannot get my 270 deg servo to go past 90 deg.



I believe it's because ERLS NORMALLY send PWM signals between 988 mu - 2012 mu

on my radiolink trainsmitter I just ext the out put and it works fine.

ERLS on the other hand won't let me and when I try it doesn't work.

I have found something called "ELRS pwm switch modes" these include

Hybrid
Wide
Full Res 8ch
Full Res 16ch
Rate/2
Full Res
12ch Mixed

Does anyone know how to use them to widen the output to get full range?

I will have to play with it again, but I am guessing you have already set your outputs to +-150 for each channel you are trying to use 270.

My radio shows 732us - 2268us after extending the min/max from 100 to 150

I also have E.limits enabled....

tried those settings, but no luck

What Receiver are you using? There may be settings on the web config page for it. Busy getting packed for Flite Fest but if I come across my ER5 between now and then I'll plug some servos in and do some testing.

Looks like you need to select extended pulse width on the receiver.

Jumper tlite v2 transmitter and a generic receiver

Kinda need more detail than generic receiver. Can you attach to the web interface on it?

 

[joortiz22]

these are the only options
